Description

Technical Field

[0001] The utility model belongs to the technical field of motor production, and specifically relates to a punching device for a motor housing. Background Technique

[0002] The motor housing is an important part of the motor. It usually plays the roles of protecting the internal components of the motor, dissipating heat, and fixing the motor structure. Punching the motor housing is a process in the manufacturing process. After the motor housing is produced, it needs to be punched as an installation point for fixing the motor or connecting other components.

[0003] Most punching devices are composed of a machine body, a punching mechanism, a driving mechanism, a positioning mechanism, etc. When punching the motor housing, the housing is placed on the machine body, clamped and fixed by the positioning mechanism, then the motor in the driving mechanism drives the drill bit to rotate, and then the push rod is used to push the drill bit to contact and penetrate the motor housing material to form a hole, thus completing the punching work of the housing.

[0004] In the current prior art, when the traditional motor housing punching device is working, in order to ensure the stability of punching, most of the punching mechanisms are fixed in the device. When the size specifications of the motor housing change, workers need to adjust the punching mechanism in time. And because the structure is mostly relatively cumbersome, it will waste a lot of time and energy of workers and cannot be adjusted quickly, affecting the practicability of the device and reducing the punching efficiency of the motor housing.

[0005] Therefore, a punching device for a motor housing is proposed to solve the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the prior art and solve the above problems, a punching device for a motor housing is proposed.

On the top of the turntable, there is a housing. On one side of the machine body, a second hydraulic push rod is fixedly connected. At one end of the second hydraulic push rod, a connecting plate is fixedly connected. One end of the connecting plate is rotatably connected to a pressing block. One side of the pressing block is in close contact with one side of the top of the housing.

[0008] Preferably, at both ends of the inner wall of each sliding groove, a sliding rod is fixedly connected. On the outer wall of each sliding rod, a sliding block is slidably connected. Each sliding block slides inside the sliding groove through the sliding rod.

[0009] Preferably, on one side of every two sliding blocks, it is fixedly connected to a movable block. Each movable block is slidably connected to the inner wall of the sliding groove through two sliding blocks.

[0013] The beneficial effects of the present utility model:

[0014] The utility model provides a punching device for a motor housing. By the contraction or extension of an electric push rod, a movable block can be driven to move inside a sliding groove. The connection between the sliding blocks fixed on both sides of the movable block and the sliding rods is utilized to prevent the movable block from being misaligned during movement.

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Please refer to Figure 1 - Figure 4 , the present utility model provides a punching device for a motor housing, including a machine body 1. Four corners at the top of the machine body 1 are fixedly connected with positioning columns 2, and the tops of the plurality of positioning columns 2 are fixedly connected with a top plate 3. A hydraulic push rod 4 is fixedly connected to the middle of the top plate 3, and one end of the hydraulic push rod 4 is fixedly connected with a connecting frame 5. A push plate 6 is fixedly connected to the bottom of the connecting frame 5, and the inner walls of the four corners of the push plate 6 are all slidably connected with the outer walls of the positioning columns 2. Two sliding grooves 7 are formed in the middle of the push plate 6, and movable blocks 10 are sleeved inside the two sliding grooves 7. An electric push rod 9 is fixedly connected to one side of each movable block 10, a positioning block 8 is fixedly connected to the middle of each electric push rod 9, and one side of each positioning block 8 is fixedly connected with the push plate 6. A driving motor 11 is fixedly connected to the inner wall of each movable block 10, and a long drill bit 12 is fixedly connected to one end of each driving motor 11. A turntable 14 is arranged below the two long drill bits 12, and the bottom of the turntable 14 is rotatably connected with the inner wall of the top of the machine body 1. A housing 13 is arranged on the top of the turntable 14, and two limiting plates 15 are snap-connected to the inner wall of one side of the turntable 14. One side of each of the two limiting plates 15 is in contact with the housing 13, and the housing 13 is arranged directly below the long drill bits 12 through the two limiting plates 15. A second hydraulic push rod 16 is fixedly connected to one side of the machine body 1, and one end of the second hydraulic push rod 16 is fixedly connected with a connecting plate 17. One end of the connecting plate 17 is rotatably connected with a pressing block 18, and one side of the pressing block 18 is in contact with one side of the top of the housing 13.

[0026] During operation, by placing the housing 13 on top of the turntable 14 and pushing the housing 13 against one side of the two limit plates 15, the limit plates 15 can be used to quickly position the housing 13 and reduce the occurrence of misalignment. Then, by the contraction of the second hydraulic push rod 16, the connecting plate 17 is driven to fall, so that the pressing block 18 lands on the top of the housing 13, and thus the housing 13 can be pressed to prevent misalignment during the punching process. Then, two drive motors 11 are started. The output shafts of the drive motors 11 drive the long drill bits 12 to rotate. Then, the hydraulic push rod 4 is used to push the connecting frame 5 to drive the push plate 6 to fall. The positioning posts 2 can prevent the push plate 6 from being misaligned during movement. So that the two long drill bits 12 can stably contact the positions of the housing 13 to be punched and form holes after penetration. Then, by the retraction of the hydraulic push rod 4, the two long drill bits 12 are lifted. Then, the rotation of the turntable 14 drives the housing 13 to rotate. By the mutual cooperation of the second hydraulic push rod 16, the connecting plate 17 and the pressing block 18, when the housing 13 rotates, it can drive the pressing block 18 to rotate inside one end of the connecting plate 17, which can prevent the housing 13 from being misaligned when adjusting the punching position. After the angle adjustment is completed, the hydraulic push rod 4 is used again to push the two long drill bits 12 to contact the housing 13, and punching is performed again, thus completing the punching work of the housing 13. When the size specification of the housing 13 changes, the positioning block 8 can ensure the stability of the electric push rod 9. Then, by the contraction or extension of the electric push rod 9, the movable block 10 can be driven to move inside the chute 7, and thus the distance between the two long drill bits 12 can be quickly adjusted. Then, the two limit plates 15 are pulled out from the top of the turntable 14 and inserted into the appropriate positions, which can meet the punching requirements of the new housing. This not only facilitates the workers to quickly adjust the equipment, reduces the physical strength and time consumed, but also improves the practicability of the equipment and the punching efficiency of the motor housing.

[0027] Further, as Figure 2 and Figure 3 shown, fixed to the inner walls at both ends of each chute 7 are sliding rods 71. Sliding on the outer walls of each sliding rod 71 are sliding blocks 72. Each sliding block 72 slides inside the chute 7 via the sliding rod 71. Fixed to one side of every two sliding blocks 72 is an activity block 10. Each activity block 10 slides on the inner wall of the chute 7 via the two sliding blocks 72.

[0028] During operation, when the movable block 10 is driven to move by the telescopic movement of the electric push rod 9, the connection between the slider 72 fixed on both sides of the movable block 10 and the slide rod 71 is utilized, so that the movable block 10 can slide stably inside the chute 7, preventing the movable block 10 from being misaligned during the movement. Moreover, the use of the slider 72 can further ensure the stability of the movable block 10, preventing the movable block 10 from shaking or being misaligned when the driving motor 11 drives the long drill bit 12 to drill holes in the housing 13, which can improve the service life and drilling effect of the equipment.

[0029] Furthermore, as Figure 4 shown, a spring 19 is sleeved outside the second hydraulic push rod 16. One end of the spring 19 is fixedly connected to the connecting plate 17, and the other end of the spring 19 is fixedly connected to one side of the machine body 1. One end of the connecting plate 17 is fixedly connected with a positioning rod 20, and the outer wall of the bottom of the positioning rod 20 is slidably connected with the inner wall of the machine body 1.

[0030] During operation, when the connecting plate 17 is driven to move by the telescopic movement of the second hydraulic push rod 16, the elastic force of the spring 19 can be utilized to improve the seismic resistance effect between the structures and extend the service life of the structures. By using the connection between the positioning rod 20 and the inner wall of the machine body 1, it can prevent the connecting plate 17 from being bent or misaligned after the pressing block 18 contacts the housing 13 driven by the connecting plate 17, so that the pressing block 18 stably fits on the top of the housing 13, which can improve the stability of the structure.

[0031] Working principle: By placing the housing 13 on the top of the turntable 14 and pushing the housing 13 to fit against one side of the two limit plates 15, the housing 13 can be quickly positioned. Then, the contraction of the second hydraulic push rod 16 drives the connecting plate 17 to fall, and the spring 19 is used to improve the seismic resistance effect between the structures. The positioning rod 20 is used to make the pressing block 18 stably fit on the top of the housing 13, and then the housing 13 can be pressed. Then, two driving motors 11 are started, and the output shafts of the driving motors 11 drive the long drill bits 12 to rotate. Then, the hydraulic push rod 4 is used to push the connecting frame 5 to drive the push plate 6 to fall, and the positioning column 2 can prevent the push plate 6 from being misaligned during movement. So that the two long drill bits 12 can stably contact the position to be drilled on the housing 13 and form holes after penetration. Then, the two long drill bits 12 are lifted by the retraction of the hydraulic push rod 4, and then the turntable 14 is rotated to drive the housing 13 to rotate. When the housing 13 rotates, it can drive the pressing block 18 to rotate inside one end of the connecting plate 17. After the angle adjustment is completed. The hydraulic push rod 4 is used again to push the two long drill bits 12 to contact the housing 13, and drilling is carried out again, thus completing the drilling work of the housing 13. When the size specification of the housing 13 changes, the positioning block 8 can ensure the stability of the electric push rod 9. Then, the contraction or extension of the electric push rod 9 can drive the movable block 10 to move inside the chute 7. The connection between the slider 72 fixed on both sides of the movable block 10 and the slide rod 71 enables the movable block 10 to slide stably inside the chute 7, preventing the movable block 10 from being misaligned during movement. Thus, the distance between the two long drill bits 12 can be quickly adjusted. Then, the two limit plates 15 are pulled out from the top of the turntable 14 and inserted into the appropriate positions, which can meet the drilling requirements of the new housing, and thus complete the adjustment work of the equipment.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
